These terms can be computed element-wise (in a similar manner as described in Section REF ) and are similar to local-projection stabilization techniques; see, e.g., [1]}, [2]}. We note that the (strong) aggregated finite element method of Section REF 
is formally recovered in the limit \(\tau _j \rightarrow \infty \) . Thus, the stabilization method is also accurate for large values of \(\tau _j\) . This last statement does not hold for other forms of the ghost penalty, in which a large parameter can constrain too many degrees of freedom, which inhibits the accuracy [3]} and is referred to as locking in [4]}. Detailed analyses and experimentation with this type of stabilization can be found in [5]} and [4]}.
